           Summary: kontact abort on close from KMKernel::cleanup
           Product: kontact
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: usenbinz at gmx.de


Version:            (using KDE 4.2.4)
OS:                Linux
Installed from:    Ubuntu Packages

Kontact had been open when the system was suspended. Upon resume kmail managed
to retrieve new mails from a POP3 account, but apparently could not reconnect
to an IMAP account. Closing and restarting kontact/kmail usually brings back
the IMAP connection. This time upon close kontact ran into an assertion on
Plugin unload:
